To whom. it may concern Be it known that I, WILLIAM N.

Figur-e2' is an elevation ofthe same, with the lock.-

covering plate removed.

Like letters indicate like part-.s in each figure.

,The nature of this invention relates to an improvement in the construction of hasps generallyl used for closing and locking gates, barn-doors, 811e.

IThe in-ventiou consists in forming the hasp with a cylindrical lock-case, a bolt or tumbler, key-stump,

4and tumbler-studs, and providing the latch-(log with a locking-ring, placed within the lock-case, and operating as more fully hereinafter set forth. E

A represents a hasp,'suspended at one end to the n gate or door by a staple, IB.

The other end is slotted, to engage with' a staple, C, in the door-frame or gate-post.

'lhe central portion of the hasphhas formed on and with it a cylindrical case, D, provided witha suitable cover, D. "lhe wall of the case is ont ont or slotted on the` side tolward the slotted end of the hasp.

In the center of the case rises a key-stump, ct, an d at either side thereof a tumbler-stud, b, in recesses in Vthe tops of which are laid the straight ends of the' bolt or tumbler E.

F is a double-headed or reversible' latch-dog, lying on the hasp, and engaging with the staple O.

The rear end of the dog projects from a cylinder, F', within the lock-case, through the opening above referred to.

4 In the bottom of the cylinder F isa cross-bar, which is journaled on the key-stump, on which it oscillates freely, as far as the opening in the lock-case will allow.

. -In the upper periphery of thecylinder l1" is formed a pair of' notches, c, into one of which enters the rear end of the tumbler-bolt when shot back with a properV key. One of the notches receives the bolt when the dogengages with its staple from above, and the other Y lhe construction and arrangement of the lock-case l D D', key-stump a, bolt or tumbler-studs b b, andtnmbler E with the hasp A, and the notched cylinder E with the latch-dog l*` appended thereto, asV and for the purpose set forth.
